This is an excellent way to teach your students how to remember the BK+TC=I Inference equation from Comprehension Toolkit! My students came up with Burger King for Background Knowledge and Taco Casa for Text Clues. They think it's hilarious and it is a sure fire way for them to remember what to put together to make and inference.
My students love when I ask them what their "Burger King" is on a subject and if they found any "Taco Casa" or text clues to help them infer. It is a sure fire way to fun teaching and one that students will not forget, at that!
